Abstract

New regression equations for estimating the bending strength of green mortar composite from pH of green cement containing fine marble particle (MP) is discussed in this experimental study. The tested properties are the bending strength of MP-green cement mortar composite at 7d, 28d, and 90d as well as pH of MP-green cement. Estimation of bending strength gain from pH is explained as new non-destructive method. In the light of the result, the substitution of marble particle up to 35% for Portland cement does have effect the performance of green cement, green mortar composite, and Portland cement positively. Green cement and green mortar composite containing up to 35% MP exhibits enhancement in pH and bending strength at 7d, 28d, and 90dwhen compared to the Portland cement and mortar composite. For that reason, the new regression equations are necessary for estimating the bending strength of MP-green cement mortar composite from pH of MP-green cement.
